DETAILED DESCRIPTION OF THE INVENTION
The embodiments of the illuminated human-machine interface device of the present invention can be keyboards or mice; the followings disclose a detailed specification about a first embodiment of the present invention. The first embodiment of the present invention is an illuminated keyboard, the positions on which the fluorescent light emits from the keyboard can be chosen on plural key caps 10, referring to FIG. 1A-1C showing embodiments of key caps having fluorescent material therein of the present invention. The key cap 10 depicted in FIG. 1A is directly printed thereon with a printed symbol 20 by positive plate printing with fluorescent ink; for example, directly printed thereon with an English letter “X” as the printed symbol 20. Thereby the printed symbol 20 on the key cap 10 can emit fluorescent light A by taking advantage of the brightness of a screen of a monitor without any extraordinary illuminating equipment. Moreover, in another printing mode for the printed symbol 20 of FIG. 1A, normal ink (without fluorescent material therein) is used to do positive plate printing in the first place, then transparent fluorescent ink is used to do a second time positive plate printing. The key cap 10 shown in FIG. 1B is printed directly with the printed symbol 20 by negative plate printing using fluorescent ink, such as directly printed with the English letter “X” as the printed symbol 20 by the negative plate printing. Thereby the periphery of the printed symbol 20 on the key cap 10 can emit fluorescent light A by taking advantage of the brightness of a screen of a monitor without any extraordinary illuminating equipment to allow operation of the keyboard propitiously. And in another printing mode for the printed symbol 20 of FIG. 1B, normal ink (without fluorescent material therein) is used to do negative plate printing in the first place, then transparent fluorescent ink is used to do a second time negative plate printing. The key cap 10 shown in FIG. 1C is made of transparent plastic mixed with fluorescent material therein, hence in the same environment as above, the entire key cap 10 can emit fluorescent light A to make outstanding of the printed symbol 20 on the key cap 10.
The second embodiment of the present invention is an illuminated keyboard, the position on which the fluorescent light emits from the keyboard can be chosen on an upper cover 30, referring also to FIG. 2A-2C which show embodiments of upper covers 30 having fluorescent material therein of the present invention. The upper cover 30 depicted in FIG. 2A is directly printed thereon with a printed symbol 20 by positive plate printing with fluorescent ink; for example, directly printed thereon with the English letters “WWW” as the printed symbol 20. Thereby the printed symbol 20 on the upper cover 30 can emit fluorescent light A by taking advantage of the brightness of a screen of a monitor without any extraordinary illuminating equipment. Moreover, in another printing mode for the printed symbol 20 of FIG. 2A, normal ink is used to do positive plate printing in the first place, then transparent fluorescent ink is used to do a second time positive plate printing. The upper cover 30 shown in FIG. 2B is printed directly with the printed symbol 20 by negative plate printing using fluorescent ink, such as directly printed with the English letters “WWW” as the printed symbol 20 by the negative plate printing. Thereby the periphery of the printed symbol 20 on the upper cover 30 can emit fluorescent light A by taking advantage of the brightness of a screen of a monitor without any extraordinary illuminating equipment to allow operation of the keyboard propitiously. And in another printing mode for the printed symbol 20 of FIG. 2B, normal ink is used to do negative plate printing in the first place, then transparent fluorescent ink is used to do a second time negative plate printing. The upper cover 30 shown in FIG. 2C is made of transparent plastic mixed with fluorescent material therein, hence in the same environment as above, the entire upper cover 30 can emit fluorescent light A to make outstanding of the printed symbol 20 on the upper cover 30.
The third embodiment of the present invention is an illuminated keyboard, the position on which the fluorescent light emits from the keyboard can be chosen on an additional fluorescent plate 40 with fluorescent material therein, the fluorescent plate 40 has thereon a plurality of hole regions 40a in corresponding by position respectively to a plurality of hole regions 30a for keys; in assembling the keyboard of the present invention, the fluorescent plate 40 is placed on the upper cover 30. The fluorescent plate 40 of the present invention can have its surface contacting with the upper cover 30 applied with fluorescent ink, please refer to FIG. 3 A which shows the fluorescent plate 40 of the present invention applied with fluorescent ink. And more, the fluorescent plate 40 can be made of some material mixed with fluorescent material therein, please refer to FIG. 3 B which shows the fluorescent plate 40 of the present invention mixed with fluorescent material therein. By virtue that the fluorescent plate 40 both have fluorescent material therein, the fluorescent plate 40 will emit fluorescent light by taking advantage of the environment of brightness of fluorescence of a screen of a monitor without any extraordinary illuminating equipment, so that the entire keyboard of the present invention can obtain an effect of a fluorescent keyboard.
FIG. 4 depicts a mouse of the present invention with a housing 50 having fluorescent material therein, the housing 50 of the mouse of FIG. 4 has fluorescent material therein and thereby can emit fluorescent light A under the environment of brightness of fluorescence of a screen of a monitor, so that the mouse can obtain an effect of a fluorescent mouse. The fluorescent material added and mixed in the housing 50 can be added only to the pressing areas including the left push button, the right push button and the middle push button, in this way, the mouse of the present invention can get fluorescent effects at these push buttons. The fluorescent material added and mixed in the housing 50 can also be added to the entire housing 50, thereby an effect of shining mouse can be obtained under the environment of brightness of fluorescence of the screen of the monitor.
Whether the illuminated human-machine interface device of the present invention is a keyboard or a mouse, the fluorescent material therein is preferably fluorescent material capable of being effective for use for a long time such that fluorescence can exist to emit for a long time, thereby the illuminated human-machine interface device can be more sustained for operation in an environment of using same as that stated before.
In addition to that the illuminated human-machine interface device of the present invention needs no extraordinary illuminating equipment, but it (especially when it is a keyboard) directly takes advantage of the brightness of a screen of a monitor to afford operation of the illuminated human-machine interface device; the illuminated human-machine interface device of the present invention can similarly work under an environment lack of illuminating equipment or provided with no illuminating equipment.
It will be apparent to those skilled in this art that various equivalent modifications or changes can be made to the elements of the present invention without departing from the spirit and conception of this invention. Accordingly, all such equivalent modifications and changes shall fall within the scope of the appended claims.
